Abstract (en)
[origin: EP3337037A1] A Doherty amplifier module includes first and second amplifier die. The first amplifier die includes one or more first power transistors configured to amplify, along a first signal path, a first input RF signal to produce an amplified first RF signal. The second amplifier die includes one or more second power transistors configured to amplify, along a second signal path, a second input RF signal to produce an amplified second RF signal. A phase shift and impedance inversion element is coupled between the outputs of the first and second amplifier die. A shunt inductance circuit is coupled to the output of either or both of the first and/or second amplifier die. Each shunt inductance circuit at least partially resonates out the output capacitance of the amplifier die to which it is connected to enable the electrical length of the phase shift and impedance inversion element to be increased.
